Referring more 1n detail to the drawings,

ythe numeral 1 denotes the steam inlet (shown moreclearly in Figure'2) leadingto/the wet steam. chamber 3 communicating with the steam superheating chamber v4 by the nipple 43; ,and 2 th'e yfinal outletof the superheated steam from the chamber v4 to convey the same tothe channel 5 .of the steam nozzle. The outlet or nipple ex-v tends froin the annular superheating chamber 4 of'the casting 27 into which chamber the steam flows after having passed through theJA annular wet steam chamber 3 ofthe casting 28coinmunic`ating 'as stated with the inlet 1. The chambers Stand 4 are respectively formed in the two sections 27 and 28 ofk a hollow wall which ksections are rigidly p attached together.

The steam nozzle 6 and oil valve 14 are held inthe casting 24 and are formed with a longitudinal channel in which is located a casing 15 tapered at itsinner end, the other extremity terminating in a hexagonal nut 15. lThe casing 15 is screwed to a housing 2O at the inner end of which is a fiance 20 having orifices 21. The housing 2O ias a channel 9 which communicates with the oil inlet 8. ,In the said housing works an. latl-i justabler rod 10 provided at its outer 'end with a radio dial 4 6 for convenience in adjustment and being screwed intothe said housing. p

The rod 10 has Va longitudinal bore 11 and a transverse bore 12 communicating withA the same and with the channel 9 of housing 20, and also another transverse bore 13 com-v municating with the bore 11 and with the interior chamber of the casing 15.' The inner end of the bore 11 isl closed by aneedle valve y14 the conical end of which enters the tapering mouth or valve seat of the casing 15. A washer 16 encloses the end of the needle valve and is held in position by a surrounding hexagonal nut 17 screwed to the casing 15 and having an orifice larger than the port or seat of the oil valve 14.

A metallic and preferably copper envelope or casing 18 is held by the nut 17 snugly against the casing 15, which envelope encloses a heat insulating material 19, as magnesia, to keep the oil supply cool. At the inner end of the copper envelope 18 and surrounding the same is a tapering steam nozzle 6 seated in the casting 24 and having slots or orifices 7 which are not only made tapering but also have a tangential slant, which orifices communicate with the interior annular channel 5 passing around the nozzle 6 and connected with the outlet nipple 2. Packing 45 is preferably used to seal the inner end of the steam nozzle 6.

ln order to prevent an undue amount of heat generated by the burner from creeping back to the source of oil supply I reduce the metal adjacent to the oil supply by making the orifices 2l of the flange 20 as large as the stability of the structure will permit and insert an as estos ring 22 between the cap 23 and the casting 24 to which it is attached to snugly hold the various parts of the nozzles together in operative position. The said cap 23 is also formed with a large central opening z3 and the casting 24 is also made with orifices 25, all of the said openings serving to reduce the metal and thereby keep the metal parts near the oil supply as cool as possible under working conditions. The nozzles comprising the oil valve and steam nozzle are placed at one side of the mixing chamber 47 and the air passage 40.

rilhe hollow castings 27, 28 and 24 are held together by stud bolts 30, the castings 27 and 28 having between the same al heat in- -sulating ring 29. A conical or dome shaped casting or distributor 33 is screwed on the upwardly extending and contracted goose neck wall of the channel ascending from the mixing chamber 47 of the casting 24. At the said oint is screwed a tapered tube 34 forming between the latter and the casing 33 an intermediate chamber 35. A gas outlet from the chamber 35 is formed by the orifices 36 in the lower part of the wall of the latter.

In the annular combustion chamber 41 formed by the cast-ings 27 and 28 I locate a perforated screen or baffle in order to diffuse and distribute air from the lower open portion or air passage 40 of the casting 28 to the base of the combustion chamber 41 formed by the said baffle. l prefer to use a plurality of screens of different mesh, as the screens 37, 38, 39, the orifices in the same being each of increased diameter from the ones below the same or of progressively larger mesh from the lowest to the highest, in order to thoroughly diffuse the air in adequate volume yet sluggishly to the whole base of combustion. The grate is held in an air tight relation and the junction between the grate and the burner is also air tight, the grate line being indicated by the numeral 42.

A partition 44 is formed in the chamber 4 and a partition 49, straddling the goose neck, is set up in the chamber 3. I also prefer to provide at least one compartment 48 between the castings 24 and 28 to contain yieat insulating material. The numeral 26 represents my emergency drain for the chamber 27.

The steam from the inlet 1 first enters the wet steam chamber 3 and from there, on account of the partition 49 in the same, is forced to pass into the superheating chamber 4, and thence, by reason of the partition 44 therein, it is led through nipple 2 and4 channel 5 formed between the steam nozzle 6 and the outlet 2 to the spraying orifices 7, the walls of the chambers 3 and 4 serving to enclose the combustion chamber and, together with the chambers 3 and 4 containing flexible devices to form a plurality of channels, to divide the fluids passing through the same, as the wires 32 which may be entered through orifices as 3l. Y

The oil enters the mixing chamber 47 from the needle valve in a stream or jet of suitable small size, where it is met by the various superheated currents emanating from the orifices 7 of the nozzle 6. On account of the tapered position of the said orifices the steam currents will converge, and by reason of the tangential inclination of the said orifices the said steam currents will also have a rotary movement. On account of this double movement of the steam` sprays the oil will become thoroughly mixed wit-h the same 4and gasified in the mixing chamber thence passing to the distributor 33.

By the means described the oil is kept so cool as to prevent any carbonization of the same to clog the valve, thereby ensuring a long life to the efficiency of the burner. The oil valve comprises a needle valve seated in the steel shell or casing 15 and adapted to be removed without taking the apparatus apart.

The gas comprising the commingled oil, gas and steam passes from the mixing cha1nber up into the tube 34 of the superheating gas chamber 35 and escapes through the oril'ices 36 into the base of the combustion chamber. Here the superheated gas is met by the air currents or streams entering through the practically unobstructed air passage 40 and thence rising from the perforated screens in such adequate quantity and sluggishness of movement as to cause all of the minute particles of oil gas to bc burned under adequate pressure with an intense blue flame without the creating of any les deposits of carbon whatsoever. The burner may be lighted by any suitable or desired means such as are in common use.

I wish it to be understood that I do not desire to limit myself to the particular use or the exact details of construction shown and described, for obvious modications will occur to persons skilled in the art.
